Description
Summary:	Cardiac catheterization in a patient with recent-onset unstable angina demonstrated a suboccluded dominant right coronary artery (RCA), with angiographic evidence of a large thrombus load and a severe focal stenosis of the left anterior descending (LAD) coronary artery. After abciximab, uneventful PTCA and stenting of the LAD was performed. The thrombus containing lesion of RCA was treated with balloon predilatation and stent deployment, and the whole procedure was accomplished with protection of the distal vessel by means of PercuSurge. This device was planned to avoid distal debris migration during percutaneous interventions of saphenous bypass grafts. The system is designed to allow the placement of a temporary occlusion device, a low-profile balloon, distal to the lesion to be treated during the procedure. The occlusive balloon is kept inflated during the treatment of the lesion. Before deflating the balloon and allowing blood to reach the distal vessel, whenever it is necessary, the material proximal to the balloon is aspirated through a monorail catheter. This aspiration removes blood and thrombi proximal to the occlusive balloon from the treated coronary artery. The case we present first reports the application of the device in a large native coronary artery, with an optimal distal flow restoring and no evidence of thrombus embolization. This type of protection of distal coronary vessels towards micro- and macroembolization of thrombi is a promising system of performing safer percutaneous interventions, even in acute ischemic syndromes.
